DRIPWATER SAFE.

Application filed July 9, 1921.

To all whom it may concern:

Be it known that I, JOHN J. Hioxmf, a citizen of the United States, residing at the city of New York, in the county of New York and State of New York, have invent ed certain new and useful Improvements in Drip-Water Safes, of which the following 'eral features of construction is a specification.

This lnvention relates to sanitary engineering and has particular reference to 1111- 'provements in plumbing apparatus associ-' ated particularly with ice boxes, I'GTfIlgGl ators, or the like for privatev residences, apartment houses, or other analogous appointments.

The invention comprises a number of specific details of construction involving the making of the pan portion of the safe of relatively thin material such as sheet metal which is adapted to be spun or pressed into form, prefe 'ably the latter, because of sev employed which render it inexpedient for spinning with the simplest possible program or manufacturing proces More definitely stated the invention comprises a drip water-pan pressed from sheet metal and having made as an integral part of the stamping an extension leading downward from the depressed central part ofthe pan, the extension being provided with parts of two different diameters and each part being threaded, all as will be more fully set forth and claimed hereinafter.

Another object of the invention is to provide a peculiar arrangement of guard or strainer for the collection of sediment or scum and with a novel arrangement of means for connecting the strainer to or supporting it above the central portion of the an. H

With the foregoing and other objects in view the invention consists in the'arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which Figure 1 is a side elevation of a preferred embodiment of the invention;

cially the manner of supporting the strainer and the threading of the pan extension.

As indicated above the pan lOis preferably made of sheet metal, either pressed or spun, but it is to'be understood thatl do not propose to be limited 'in all instances'to any particular species of material or specific manner of construction or forming of the device. For the mostsatisfactory pracent diameter but indicated as. sn'iallerthan.

the main extension 11.

.tice "of the invention the combined pan and The extension is formed as a continuation of the central pocket or depressed portion 10 of the pan, and leading into the extension are oneor more channels orvalleys 12 of any suitable length, cross sectional form, or direction, but indicated as being formed substantially radially with respect to the ex tension and leading thereinto from about the upper edge of the depressed pocket por-,

tion 10. These channels constitute drainage passageways for the drip water and so in a marked degree tend to prevent the clogging or stoppage of thexdrain because of any accumulations of slime, scum, or the like withinthe pan. 'Moreover, these valleys 12 may readily be formed coincident with the simple stamping operation.

The extension 11 may be provided with screw threads 011 the inside or outside or both; As indicated such threads are shown inside at 13 and outside at 1 1. The inside thread may be used for the attachment of an upstanding pedestal or guard in some instances, or if the auxiliary extension is not used, a delivery pipe may be attached to extend downward therefrom. The outside thread 14 will ordinarily be employed for the connection of a supporting drainage pipe, either by means of an inside thread formed in such pipe or through a nipple or coupling specially provided for this purposeor any other well known means. lVith the provision of the extension 11 I prefer to provide an inside thread 15 and an outside thread 16, through either of which threads a supporting drainage pipe may be connected, such pipe obviously being of smallerdiameter'than the pipe that would ordinarily be connected to the main extension 11.. i

For the best or most successful operation of drip water safes it is desirable to provide some suitable guard means within the pan and yet below the level of the upper edge thereof to'receive and check the accumulations of scum or the like which Otherwise would soon fill up the outlet opening of the pan and so cause the pan to overflow. For this purpose I indicate a strainer 17 in the form of a flat cap or comprising acentral dome portion having any suitable holes 01' slots 18 and a peripheral flange 19 for attachment or supporting purposes. This strainer may be attached directly to the inner surface of the pan, but preferably it is held elevated above or spaced from said inner surface. If the strainer be supported directly upon the pan the drainage valleys 12 would still afi'ord fairly satisfactory flow of the water without obstruction. vThe means I indicate for attaching the strainer consists of a plurality of posts20 tapped into a like number of extrusions 21 punchedor stamped downward from the bottom portion of the pocket 10*" of the pan, this operation being performed coincident with the stamping of the pan. The tapping of these extrusions is easily and quicklyperformed thereafter. The posts 20 extend downward through the strainer flange 19.- Any suitable means may be provided to hold the strainer elevated or against the upper headed ends of the posts, but I preferably support the same both resiliently and adjustably, the

resiliency being effected by co-iltsprings surroundlng the posts and bearing upward against the bottom of the flange, whilethe adjustability of the strainer, making the clearance at 23 greater or less, is accomfrom the pan.
